Who: Bella Hadid.
When: Tuesday, May 17.
What: A matching blazer and trousers with fringed top, all by Givenchy, with shoes by Giuseppe Zanotti.
Why: After flying to Sydney for a quick appearance at Australia Fashion Week (where she appeared at the Misha Collection show, accompanied by an all-white cast of models walking to the tune of Beyoncé's "Formation" — a move that immediately drew criticism), Hadid jetted over to Cannes for the decadent and model-populated de Grisogono party. But among a high-wattage group of attendees, Hadid's showy, sparkly take on the suit that has dominated the red carpet this year still seized the spotlight.
